Protein-based bioplastics: effect of thermo-mechanical processing

Modelling of pyrolysis and combustion of gluten–glycerol-based bioplastics

“…The mixing process was always carried out at 50 rpm (Jerez et al, 2005a). In order to get a bioplastic with suitable mechanical properties, the mixed product was subsequently moulded in a hot-plate hydraulic press, at 100 bar gauge pressure and 140°C (Jerez et al, 2005b). Bioplastic moisture concentration was gravimetrically determined by heating samples of bioplastics in a ventilated oven at 110°C for 24 h. For both bioplastics, BWG05 and BWG06, the calculated moisture content was 10 wt.%.…”

A review of the recent developments in biocomposites based on natural fibres and their application perspectives

“…Soy protein can be processed using existing plastic processing technologies: from the physicochemical or film casting method [59] to thermoplastic/mechanical method (extrusion or compression moulding) [60]. However, common processing technique, such as injection moulding has not been found to be useful for the processing of protein-based bioplastic applications [60].…”

Influence of sorbitol on mechanical and physico-chemical properties of soy protein-based bioplastics processed by injection molding

“…This SB saturated solution was used as plasticizer, and was introduced in a ratio of 50/50 (SPI/plasticizer). The specific mechanic energy (SME) of mixing (Equation 1) may be defined as follows [16] :…”
